DTC Fault Trigger Conditions






Pinpoint Test

1. CHECK FOR RECORDED DTCs (Diagnostic Trouble Codes) FROM BOTH THE CONTINUOUS AND ON-DEMAND PAM (Parking Aid Module) SELF-TESTS

1. Using a scan tool, perform PAM (Parking Aid Module) self-test.

Is DTC (Diagnostic Trouble Code) B129F:11 or DTC (Diagnostic Trouble Code) B129F:12 recorded?






2. CHECK THE ACTIVE PARK SWITCH LED (Light-emitting Diode) STATUS CIRCUIT FOR A SHORT TO VOLTAGE

1. Ignition OFF.

2. Disconnect: PAM (Parking Aid Module) C4014A.

3. Ignition ON.

Is the active park assist switch status LED (Light-emitting Diode) still illuminated?






3. CHECK FOR DTCs (Diagnostic Trouble Codes) WITH THE ACTIVE PARK ASSIST SWITCH DISCONNECTED

1. Ignition OFF.

2. Disconnect: Active Park Assist Switch.

3. Using a scan tool, perform PAM (Parking Aid Module) self-test.

Is DTC (Diagnostic Trouble Code) B129F:11 still present?






4. CHECK THE ACTIVE PARK ASSIST SWITCH LED (Light-emitting Diode) STATUS CIRCUIT FOR A SHORT TO GROUND

1. Disconnect: PAM (Parking Aid Module) C4014A.

2. Measure:





Is the resistance greater than 10,000 ohms?






5. CHECK THE ACTIVE PARK ASSIST SWITCH LED (Light-emitting Diode) STATUS CIRCUIT FOR AN OPEN

1. Disconnect: Active Park Assist Switch.

2. Disconnect: PAM (Parking Aid Module) C4014A.

3. Measure:





Is the resistance less than 3 ohms?






6. CHECK THE ACTIVE PARK SWITCH GROUND CIRCUIT FOR AN OPEN

1. Measure:





Is the resistance less than 3 ohms?






7. CHECK FOR CORRECT PAM (Parking Aid Module) OPERATION

1. Ignition OFF.

2. Disconnect and inspect the PAM (Parking Aid Module) connectors.

3. Repair:

- corrosion (install new connector or terminals- clean module pins)
- damaged or bent pins- install new terminals/pins
- pushed-out pins- install new pins as necessary

4. Reconnect the PAM (Parking Aid Module) connectors. Make sure they seat and latch correctly.

5. Operate the system and determine if the concern is still present.

Is the concern still present?
